**Acknowledgements**

I want to especially thank my patients who throughout these two years of being a rheumatologist have taught me important life lessons. Thanks to them we are here. Thanks to my teachers, especially doctors Carlos Abud, Enrique Cuevas, David Herrera, Ricardo Moreno, and doctor Eva Santillan from the Ignacio Morones Prieto Central Hospital**.** To my son and my husband. All my love and my affection.
